Solve the system.

x^2 + 2x + y + 8 = 0
2x - y = 4

To complete your spring schedule, you must add calculus and physics. at 9: 30, there are three calculus sections and two physics sections; while at 11: 30, there are two calculus sections and three physics sections. how many ways can you complete your schedule if your only open periods are 9: 30 and 11: 30?

The sum of these consecutive integers is equal to 9 less than 4 times the least of the integer. find the three integers

What is the 9th term in the geometric sequence described by this explicit formula? an=-6. (2)(n-1) apex
